Phase structure of (3+1)-dimensional dense two-color QCD at $T=0$ in the strong coupling limit with tensor renormalization group

We investigate the phase structure of the (3+1)-dimensional strong coupling two-color QCD at zero temperature with finite chemical potential using the tensor renormalization group method. The chiral and diquark condensates and the quark number density are evaluated as a function of the chemical potential. Our results are compared with the previous analytical results using the mean field approximation. The critical exponents associated with the diquark condensation are also discussed.
